A:  Hi Randy, Thanks for your question. The answer will depend primarily on the power requirements of your particular A/C unit in watt-hours. For example, a 15,000 BTU A/C unit running at 100% will require up to 1,500 watts per hour, or 1.5 kW. To run this unit with solar would require 1.5 kW of panels, which could be achieved as follows: 30 - 50W panels 15 - 100W panels 8 - 200W panels 4 - 370W panels This calculation assumes full direct sunlight, so if you need to run the A/C during cloudy conditions or at night, a sufficiently-sized battery storage system would also be required. Keeping the batteries charged while using the A/C could possibly create a need for additional panels, depending on the situation. Hope this is helpful. Grape support

A:  No, not that I know of !!! When I received it, it had no instructions or cables to hook it up !!!

A:  Yes, if are going to parallel them for a 12V system.. Since you have 8 panels I assume that you are going to use a charge controller that is able to handle over 40 amps (assuming 12 V at 5+ amp 100 Watt panels in parallel). Also use higher gauge cables since it over 40 amps total.

A:  Most likely, yes. The panels come with 47.2” long cables complete with MC-IV connectors. Therefore, it depends on how they will be configured (in series, parallel or combined), as well as the distance for the Charge Controller or Batteries.

A:  Yes, in a manner of speaking. "Positive and negative leads equipped with MC4-comparable connectors" Basically it's a quick connect and the other question would be series or parallel. More volts vs more amps. There are also charge controllers that are needed to charge batteries without backflow of current. This is a good way to go for off grid, backup power, or just to keep from running a generator. But do a little reading on it, plenty of websites and social media groups for answers. It'll save a bit of time and frustration.

A:  Contact Grape Solor directly for the number of panels you can connect together and wiring gage size required. 1-877-264-1014

A:  Yes and depends if you hook 2 in series for 24V strings

A:  In Series, No. In parallel, yes. Eight panels in parallel will give you some pretty serious current. The panels have a blocking diode so It will be pretty easy to connect them together.

A:  Hello, In most cases, the answer is yes. Any solar system will require a charge controller and a storage battery, and many users will also require a D/C to A/C inverter. Additional cables or connectors are required for: Battery connection Parallel panel configurations Extensions for panel arrays > 3ft from the controller How you configure 8 100W panels will depend on the input ratings of the charge controller you are using, as well as the mounting orientation of each panel.

A:  Yes you can.

A:  Look like Oregon. USA

A:  Thanks for your question! These panels are manufactured in Indonesia.
